Customers in B2B as well as B2C markets increasingly demand integrated problem solutions from their suppliers, comprising both physical artifacts (products) and services. Applying a mixed-bundling strategy to offer such value bundles to customers foremost requires a sound configuration and economic calculation of value propositions, based on previously defined modules of products and services. ...

This paper presents an integrated approach to support both top-down and bottom-up design of software systems by combining UML (Unified Modeling Language) and the Formal Engineering Method SOFL (Structured Object-oriented Formal Language). We demonstrate by examples that the topdown principle used in conventional Structured Design can be effectively utilized to carry out ObjectOriented design th...

This article proposes a modeling language for developing concurrent software, Object-Oriented Petri Nets (OOPN), which combines the maintainability and reusability of Object Orientation (OO) and the advantages of Petri Netsa graphical interface and a sound theoretical background. By doing so, each benefits from the other and their negative aspects are at least effectively diminished. The implem...

Management of today’s IT is a challenging task that requires a profound understanding of both the IT landscape and the relevant business context. Numerous relations and dependencies between business and IT exist, which have to be accounted for, e.g., for better IT/business alignment. This paper presents ITML (IT domain specific Modeling Language) integrated with a comprehensive method for enter...

While the demand for an integrated modeling support of business processes and corresponding security properties has been repeatedly identified in research and practice, standard modeling languages do not provide native language constructs to model process-related security properties. In this paper, we are especially concerned with confidentiality and integrity of object flows. In particular, we...

Expressive models of the work processes performed in the chemical and process industries provide a basis for diverse applications like work process documentation, analysis, and enactment. In this contribution, we present a generic modeling language for different types of work processes to allow for their integrated representation in the life cycle of a chemical plant. Further, the generic langu...

this presentation, we propose a novel integrated information retrieval approach that provides a unified solution for two challenging problems in the field of information retrieval. The first problem is how to build an optimal vector space corresponding to users' different information needs when applying the vector space model. The second one is how to smoothly incorporate the advantages of mach...

Web service technologies are becoming increasingly important for integrating systems and services. There is much activity and interest around standardization and usage of web service technologies. Contemporary web services are described in the Web Service Description Language (WSDL). However, WSDL documents can be difficult to understand for service developers. This paper recommends a modeldriv...

Versatile model-based design demands languages and tools which are suitable for the creation, manipulation, transformation, and composition of domain-specific modeling languages and domain models. The Meta Object Facility (MOF) forms the cornerstone of the OMG’s Model Driven Architecture (MDA) as the standard metamodeling language for the specification of domain-specific languages. We have impl...
